I've been looking for a free mesh tree that correctly mimics the Neem (dogoyaro) tree, something good for foregrounds. I found nice give-aways but none of them was a Neem tree, so ... i made one and I'm sharing it. This is not a full grown Neem so the crown is a bit scanty but I left a copy of the repeating leaf pattern for the designer/artist to play with (see neem-leaf_reserve). This mesh tree renders well with any choice renderer and there's no need to worry about alphas ... just put it there and hit F12. Leaves groups are linked to the trunk but all can be joined together into one mesh (ctrl+J). Feel free to experiment.
